Spark OK, Fuel pump OK, poured fuel into tb & still no start. Used a Solists scan tool & rec'd a number of codes; P0405, EGR 'A' (Short or Bad). P0339, CKP sensor 'A' intermittent. P0122 TP or APP sensor (Short or Bad). P0118 Temp sensor. P1112 TP circuit. P1115 ECT high voltage. P0440 Evap fault. P0330 Misfire. Need to know
You have an incredible amount of codes, so I would look for a abrasion in the wiring harness.
Testimonial: "Well of the couple of suggestions I rec'd were sorry to say, "not very helpful", basically after my son & I scanned it & it ran so many codes one must now think its only " 1" critical sensor that sets off the rest. I'm saying P0335 CKP sensor is the culprit, Just think about it fer a spell! It precedes the PCM & tells it what to do, so if its shorted or bad it boogers up the whole system. Setting off all kinds-o-signals because nothing is timed now. Remember that the CKP requires a shim now (should a been a recall) if they knew that. At least a .005 shim, sensor should not make contact with the reluctor wheel."

Exhaust Gas Recirculation System Is the main problem here. the other code P0118 may be a bad temprature sensor or your thermostate needs to be changed. Last it could be a weak water pump.
So what is an EGR system and how does it work? EGR stands for Exhaust Gas Recirculation, and as its name implies, this system allows exhaust gasses from your car to be re-circulated into the engine, helping to reduce emissions. These systems are mostly comprised of the EGR valve, a DPFE (Delta Pressure Feedback EGR) sensor, hoses, a vacuum regulator, some vacuum lines, wiring, the computer and the exhaust tube leading to the valve itself.
The car's wiring can be tested in the normal fashion by looking for broken and lose wire, and all vacuum lines can be checked easily for cracks, leaks and correct routing.
The last thing i would then check is the the EGR valve, EGR vacuum regulator and DPFE sensor (or similar flow sensor).
I hope this helps and good luck

Firstly, what's a TDC sensor?.. the crank position sensor? If so, on the four (4) cylinder, it's located behind the timing belt cover at the crankshaft.. if it's the 2.5 V6, it's located behind the LH exhaust manifold on the engine block.

Possible problem with the alternator not putting out enough voltage. I had the same problem with my 2002 XC70, putting in a new alternator fixed it. I used a local mechanic who I found on the car talk web-site. Low Cost Volvo parts can be purchased at FCP Groton.

Engine coolant temperature (ECT) sensor is a thermistor screwed into a coolant passage in the cylinder head. Sensor resistance is high when coolant temperature is low and resistance drops when coolant temperature increases. The powertrain control module (PCM) provides a 5 volt reference and a ground to the sensor. The PCM monitors voltage drop to determine coolant temperature. If the ECT reads less than freezing temp. when engine has been running for more than a few minutes, the PCM determines a circuit fault and sets this code. Or if the PCM determines the sensor resistance is out of specs, this code is set. The reference values given below are measured between ECM terminal 72 and ground... When measuring input / output voltage be careful not to use ECM ground terminals. The ECM will enter fail safe mode once a malfunction is detected and the MI will light up.
Usually, P0118 is indicative of a bad temperature sensor, but doesn't
rule out these other possibilities. If you're unsure of how to diagnose a PCM,
do not attempt.
